This 1975 GMC Truck 1500-3500 Service Manual Supplement to the 1974 GMC Truck Service Manual is a high-quality, licensed, PRINT reproduction of the shop manual written and first published by the experts at the original equipment manufacturer (OEM), General Motors Corporation, for use by their dealership mechanics. Now, this industry-professional tool can be yours.

NOTE: This is a SUPPLEMENT. It covers only the servicing of NEW components which differ from those instructions found in the main manual. It will frequently refer you back to the parent manual: 1974 GMC Truck 1500 - 3500 Service Manual. You will need BOTH manuals for complete service information.

Packed with over 300 pages of detailed, maintenance and repair instructions, this 1975 GMC Truck 1500 - 3500 Service Manual Supplement has the factory-correct procedures and specifications you'll need to get the jobs done right. Please scroll down to view a sample page we've included to demonstrate some of the visual tools and how well they complement the step-by-step, text instructions. In this case, it's an exploded-view, black and white photograph of the High Energy Ignition (HEI) distributor. Don't worry. You'll find charts, tables, illustrations, cut-away views and more throughout this helpful guide to assist you with jobs of all sizes from start to finish.

We love this service manual, and want to take a moment to recommend another, excellent, factory-written resource. Please check out the 1973 - 1978 Chevrolet & GMC Truck Parts Books - Text & Illustrations. It contains a wealth of information NOT found in the regular service guides.

Long overshadowed by their older brothers, these "Square Body" models have now taken their own place as super-popular classics. Featuring handsome styling and rock-solid mechanicals, it's no wonder there's such a desire to keep these machines on the road. Be sure you use the best tools available for the projects on your 1975 GMC truck. That's just what you'll get with this 1975 GMC Truck 1500-3500 Service Manual supplement (and the '74 main manual).

In 1975, the radio airwaves were frequently filled with the year's best-selling single "Love Will Keep Us Together". It was the cover version from Captain & Tennille. It's certainly a great message, but it'll probably take more than love to keep your classic GMC together after all of these decades. Who will be keeping you on track? You can almost hear this book singing..."I will, I will, I will."

This factory-written shop manual is perfect for service, repairs, restoration and rebuild projects. Clear illustrations and photos show exploded views, as well as component details, plus specifications, engine repair details, fuel systems and more.
